Remarks

Starting with Windows Internet Explorer 9, the behavior of the HTMLInputFileElementEvents::onresize event varies according to the document mode of the webpage and the registration of the event.

For webpages displayed in IE9 standards mode or later (including interoperable quirks mode), the resize event behaves according to the W3C DOM Level 3 events standards. In earlier versions of the browser (and corresponding documents modes), the resize event is a legacy, proprietary event associated with element document objects.

In practice, this means the following: As a result, the behavior of the resize event depends on two factors: the document mode of the webpage and

As of Internet Explorer 9, the type of the event object passed to a function handling the HTMLInputFileElementEvents::onresize event varies:

When the event is fired from the window object, the event object is a standards-based Event object.

When the event is fired from an element and the handler was assigned using the HTMLInputFileElementEvents::onresize attribute, the event object is a legacy event object supported by Windows Internet Explorer 8 and earlier versions of Windows Internet Explorer.

When the event is fired from an element and the handler was assigned using the IHTMLElement2::attachEvent method, the event object is a legacy event object.

For pages displayed in legacy document modes (IE8 Standards mode and earlier), the event object is a legacy event object..

When the event is fired in the context of a Windows Store app using JavaScript, the event object is a standards based Event object.

The HTMLInputFileElementEvents::onresize event fires for block and inline objects with layout, even if document or CSS (cascading style sheets) property values are changed. Objects have layout when measurements such as the IHTMLRuleStyle::height and IHTMLCurrentStyle::width attributes are set, or when the IHTMLRuleStyle2::position of the object is set. Intrinsic objects, such as button, and windowed objects, such as window and iframe, fire as expected. This event does not fire for files with embedded controls.
